That’s when he allegedly went into his 16-year-old brother’s room, told him what he had done and then said he needed help “killing the rest of them.”

Police believe he was referring to his father and a foster child who were also in the home, but the brother wrestled the gun away.

Last week, a judge did rule that Tony Day is amenable to treatment.

That means he would be sentenced as a juvenile, putting him in the juvenile detention center until he’s 21.

With that determination made, Day’s attorney, Jeff Buckels, says he plans to plead guilty to the murders sometime later this month.

“We certainly do think it’s best for everyone involved. It resolves the case first of all critical to the family of victims and of course very much in tony day’s favor because he can have a life now,” said Buckels.

Day’s attorney says Day has expressed remorse for the killings.

There has never been any real motive explained, however, Buckels did present evidence at last week’s hearing that showed Day was abused and neglected by his biological parents.

They had their parental rights terminated by the time he was 7 years old.

Buckles also claimed Day’s life at home was chaotic. He was adopted by the family two years before the killings.
